Hi!
I have such error on force connection close.
To reproduce bug run this example code and twice close connection via RabbitMQ management plugin

import asyncio
import aiormq

async def main():
    for _ in range(2):
        try:
            connection = await aiormq.connect("amqp://guest:guest@your_rabbitmq_ip/")
            channel = await connection.channel()
            await channel.queue_declare("test")

            while True:
                await channel.basic_publish(b"0", routing_key="test")
                await asyncio.sleep(0.01)

        except (BaseException, Exception) as e:
            print(f"EXCEPTION: {e}")


if __name__ == "__main__":
    asyncio.run(main())

Output
